ATTACHMENT FORv RU LING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 439,360, dated October 28, 1890.

Application led December 18, 1889. SerialNo. 334,211. (No model.) I

' To a/ZZ whom it may concern.:A

. New York, have invented a newl and useful Attachment for Ruling-Machines, of which the following is a full, clear, and exact de scription.

. My invention relates to an attachment for ruling-machines, and has for its obj ect to provide a means whereby paper may be tinted or ruled in Wave-lines and at a minimum cost, the same effect being produced that has heretofore been accomplished only by lithography and at great expense.

A further object of the invention is to provide a device of a simple character and capable of convenient attachment to any known ruling-machine.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a partial side elevation of a rulingmachine having my improvement applied, illustrating the driving mechanism. Fig. 2 is a vertical section of the, machine, taken in front of the pen-beam. Fig. 3 is an enlarged side elevation of the reciprocating mechanism of the pen-beam. Fig. 4 is afront elevation of the same. Fig. 5 is a plan view of the cam. Fig. 6 is a partial inner side elevation of the same. Fig. 7 is a front View of one of the cradles of the pen-beam, and Fig. 8 is aside view of the same. Fig. 9 is an enlarged plan view of the pen-beam, illustratingthe pens as producing the wave-lines; and Fig. 10 is a transverse section taken through the pen-beam.

The frame 10 of the ruling-machine may be of the ordinary or any approved construction, likewise the arrangement of the endless carrying-belt 11, and the binding-threads 12 may be such as are in common use. p

The machine illustrated is that well-known to the trade,.A representing the power-pulley thereof, B the thread-cylinder, and C one of the carrying-belt drums.

The pen-beam D is of peculiarpconstruction, being made in two longitudinal sections 13 and 14, which sections are hinged together, preferably at their upper faces. The section 14 is formed in two pieces a and a', held in contact by any form of clamps 15, and between the two parts a and a" the pens or pen 16 is secured.

In the contiguous edges of the beam-sections 13 and 14, registering recesses 17 are produced, and in each pair of the opposed recesses of said sections a spring 18 4is introduced, the tendency of the springs being to throw the pen-carrying section 14 upward and remove the pen from contact with the endless belt or paper placed thereon to be ruled. The springs, however, may be of a dierent character than illustrated, and may be otherwise applied.

A lock-latch of any description is applied to the beam, a simple and preferred form being illustrated in Fig. 9, consisting of a latch 19, pivoted at one end upon the rear section 13, and of sufficient length when carried transversely of the beam to extend over the pen-section 14. This latch is held in a transverse locking position, and is made to press the beam-section 14 downward and cause the pens to contact with the paper by means of a keeper 20, secured to the rear beam-section, which keeper extends over the latch. A railplate 2l is preferably attached to the pensection of thebeam, as shown in Fig. 9.

In operation, as soon as the latch is disengaged from its keeper and the pen-section the latter is forced upward by the springs and the ruling ceases. To the ends of the rear section 13 of the pen-beam horizontal arms 22 and 22`nare attached, which arms are `preferably rectangular in cross-section, and

upon each upper side rail 23 of the lmachine a cradle 24 is secured, in which cradles the arms of the pen-beam are firmly secured, the arms extending outward beyond the cradles.

The cradles are illustrated in detail in Figs.

7 and 8, and consist, preferably, of standards b, projected upward in parallel lines from a base-plate b', and between the standards the IOO lower end of a fork b2 is pivoted, the arms of the pen-beam being secured between the members of the forks of the respective cradles.

Upon that side of the machine over which the arm 22a of the pen-beam projects, and near the cradle upon that side of the' machine, the vertical member d of a bracket 25 is adj ustably secured to the outer face of the rail 23, the vertical adjustment of the member CZ of the bracket being, preferably, accomplished by producing in said member a vertical slot, and passing through the slot and into the rail a bolt 26. The horizontal member d of the bracket 25 at its junction with the vertical melnber is preferably rectangular, and round throughout the remaining portion of its length. The rectangular portion cl2 of the horizontal member of the bracket is provided with a vertical slot extending through from top to bottom, and upon the round portion of said member d of the bracket a cone-pulley 27 is loosely mounted, the inner pulley of the cone having formed integral with its inner face a cam-surface 28, the said cam-surface being undulating, as best shown in Figs. 3 and 5, comprising a series of alternately-arranged concave surfaces e and convex surfaces e. The cone-pulley and cam are held to place upon the horizontal member of the bracket by contacting with a shoulder formed by the rectangular portion d2 of said member, and by suitable lock-nuts screwed upon the outer end.

In the slotted portion of the rectangular section d? of the horizontal member of the bracket 25 a lever 29 is centrally pivoted, the said lever having mounted upon its lower end a friction-roller 30, which contacts with the undulating surface of the cam 28, and near its upper end a similar friction-roller 31 is mounted, which also contacts with the undulating surface of the cam, as illustrated in Fig. 3. rlhe lever 29 is carried above the upper friction-roller 31, and is preferably7 squared and made to pass through an opening in the arm 22 of the pen-beam, and the said squared section of the lever is provided with a series of longitudinally-arranged apertures 32. l The lever is held in connection with the arm 22L of the pen-beam by passing a pin through an aperture in said arm and through one of the apertures in the lever.

I do not conne myself to any particular mechanism for revolving the cam 28; but the preferred mechanism is illustrated in Fig. l, and consists in attaching to the lower rail 33, upon that side carrying the power-pulley A, a counter-shaft 34, and upon said countershaft a pulley 35 is keyed or otherwise attached. A second pulley 36 is loosely mounted upon the outer end of the said shaft, having a clutch-connection with the pulley 35, and the said loose pulley is carried inward to a contact with the pulley 35 or disconnected therefrom by a shifting-lever 37. (Illustrated in Fig. 2.) The fixed pulley 35 upon the counter-shaft has a belt-connection 38 with a pulley 39, fast upon the shaft, upon which the power-pulley A is secured, and the loose pulley 36 is connected by a belt 40 with the conepulley 27, carrying the cam 28.

In operation any of the usual forms of pens may be employed, and when the pens have been placed in position in the beam D and the sections 13 and 14 of said beam are locked together, as shown in Fig. 9, upon power being applied to the driving mechanism the cam 28 is rotated, and in rotating it causes the lever 29 to vibrate upon its fulcrum, and thereby imparts to the pen-beam a laterally-reciprocating vibratory movement, which causes the pens to produce the wave-lines, (illustrated at E in Fig. 9.)

The wave-lines may be shortened or lengthened by adjusting the vertical member d of the bracket 25 upward or downward upon the rail 23, and thereby increasing or decreasing .the distance between the fulcrum of the lever 29 and the point of connection between said lever and the pen-beam. The cradles 24 are employed in order that all possible friction may be avoided, to interfere in the least with the lateral movement of the pen-beam.

vI desire itfurther to be distinctly understood that while details of construction have been shown and described I do not confine myself thereto, as other equivalent construction may be employed without departing from the spirit of the invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a ruling-machine, the combination, with the frame, the vertical standards at opposite sides of the frame, and the'transverselyrocking forks or links pivoted to the standards, of a pen-beam having arms at its ends mounted on said forks or links, and mechanism for reciprocating the pen-beam, substantially as set forth.

2. The combination, with the frame and the transversely-reciprocating pen-beam having end arms mounted in bearings on the frame, one end arm projecting beyond the side of the frame, of a vertically-adjustable plate 25 on the frame under said projecting arm, a lever 29, pivoted between its ends on said plate and connected at its upper end to the said arm, and a rotary cam engaging the said lever tbove and below its axis, substantially as set orth.

3. The combination, with the frame, the cradles 24, and the transversely-reciprocatin g pen-beam having end arms 22 22a, mounted on said cradles, of the vertically-adjustable bracket 25, mounted on the side of the frame under arm 22, having a horizontal member d', squared and vertically apertured at its inner end and rounded beyond said squared portion, the lever 29, pivoted between its ends in said vertical aperture and connected at its upper end to the arm 22, and the rotary cam- IOO ' wheel mounted on the rounded part of the I a spring for pressing the section 14 away from member cl and having an undulating surface on its inner face engaging the said lever above and below its center, substantially as set forth.
